It may appear unusual to have a contribution on neutrino scattering at a school devoted to electromagnetic probes, as the neutrino has no known electromagnetic couplings. However, as a means to examine the hidden flavor currents in the nucleon, the recent results observed for the spin structure function of the nucleon have focused attention on the nucleon`s neutral weak currents (NWC). When an electromagnetic probe is scattered elastically from a nucleon, the NWC interactions are observable only through the detection of very small (> 10{sup {minus}6}) parity-violating processes. In the case of neutrino scattering, the NWC is the dominant coupling. In what follows it will be shown how the nucleon`s vector and axial vector form factors arising from strange quark currents can be measured via neutrino elastic scattering. Preliminary results from the Large Scintillation Neutrino Detector (LSND) at LAMPF will be presented as well as a recent analysis of an earlier experiment (E734) carried out at Brookhaven.
